The atmosphere and aesthetic were quite good, and there are a decent few mechanics I rather liked here. The floor where you walk crumbling on a time limit pushes you to keep moving, but also to be careful which turns you take as it is surprisingly easy to accidentally double back. Having your... sanity, I guess? drain with each step and replenish when engaging in combat also did a good job of discouraging simply ignoring and going around enemies.
However, the combat also felt a little janky due to the animations (the monsters stuttering between turning/attacking and taking damage/dying) and the buggy feedback on taking damage (the red filter would only sometimes come up, and one time it never went away). Also, sometimes there were grid squares I simply could not move through, and sometimes the collision of monsters didn't go away when they died (lost a very promising run to that bug). I think either a navigation mechanic for finding the talisman pieces or some other method of limiting how long the player can go without encountering one would also be a significant improvement - currently, it seems that the maze generation can simply not decide to give you one for rather extended lengths of time.
I recorded my full playthrough, you can take a look here if you would like:
